60" x 75' CMP with deteriorated headwall and in need of additional wing wall. We saved the City time, money, and headache on the pipe, and were even able to saw cut, demo, and remove substandard headwall, and provide additional wing wall that was needed for less than the City had budgetted for digging and replacing the pipe. As always, we didn't simply line a substandard pipe; we spincasted a new, structurally independent pipe rated to last at least 123 years.
